Hasanlu Tepe is a large, mounded archaeological site in the Azarbaijan Province of northwestern Iran near the southern shore of Lake Urmia. Hasanlu was the focus of excavations carried out by the University of Pennsylvania Museum, the Metropolitan Museum of Art of New York, and the Archaeological Service of Iran from 1956 to 1977 under the general direction of Robert H. Dyson, Jr. The purpose of this website is to present the results of the Hasanlu Publications Project, which is currently preparing the final excavation reports on the massive corpus of data produced by the excavations and archaeological surveys carried out at Hasanlu and in the surrounding region. Currently we are working on the final report on Hasanlu Period IVb, the famous citadel that was sacked and burned around 800 B.C., a veritable Pompeii of the Iron Age Near East.
